SEO is the work that makes your website discoverable and competitive in traditional search results. It focuses on crawlability, indexation, technical health, page quality, search intent, internal links, backlinks, and conversion paths.
AI SEO, also called GEO or AI visibility work, makes your brand and pages easier for AI systems to access, understand, verify, cite, and summarize correctly. It adds prompt testing, crawler access checks, answer-first page structure, entity consistency, source-gap mapping, external trust signals, and citation reporting.
The wrong question is which one replaces the other. The useful question is which bottleneck is blocking visibility right now. If Google cannot crawl, index, or trust your pages, AI SEO will not rescue the site. If you already rank but buyers now compare options through AI tools, traditional SEO alone may not show the full risk.

Google says SEO best practices remain relevant for AI Overviews and AI Mode, and supporting links need indexed, snippet-eligible pages. That is why this page treats AI SEO as an added layer, not a shortcut around search fundamentals.
